steve1 is on a distinguished road
can someone help with the pressure calculation for a simulation on the Onera M6 wing 3.06 degrees AoA, Mach 0.8395. The web site below gives the pressure as 45.83 PSI, however for a RE of 1.172E+07, MAC of 0.64607m, V of 269m/s and dynamic viscosity of 1.628E-05, I get a Density of 1.097 Kg/m^3 and therefore a pressure of 80508N/m^2 using a temp 255.5K (460 R) which is 11.68 PSI. What am I doing wrong in my pressure calc.

Thanks Steve
